First record of a-sexual reproduction by fission in Holothuria (lessonothuria) verrucosa (Selenka, 1867) from coastal waters of Karachi, Pakistan
Öz
An experiment
of a-sexual reproduction by fission was conducted on sea cucumber, Holothuria
(Lessonothuria) verrucosa (Selenka, 1867) for 98 days. Anterior fission was
observed on Day 1 with the formation of fission on the body of the sea
cucumber. Initial length of 14 cm and weight of 21 g was measured at Day 1 in
an aquarium under laboratory condition. Complete fission was observed on Day 7
of experiment by formation of 2 specimens; A and P. Initial length and weight
for A was 4.5 cm and 3.18 g, while P was 9.5 cm and 17.30 g respectively.
Increased weight for specimen A was observed on Day 20 with the first
observation of the formation of anal pore. Tentacles started to form on
specimen P on Day 34. Complete formation of anus on specimen A was seen on the 98th
day of experiment with final weight of 3.84 g and length of 4.6 cm. Large
growth of tentacle was also seen on Day 98 of the experiment with a final
weight of the specimen P as 17.56 g and length as 9.7 cm.
